A four-way multiplexing incoherent holographic device with double beam splitter ring-shaped detection

Abstract

The utility model relates to image reconstruction technical field especially relates to a four -way multiplexing incoherent holographic device of double beam splitter annular detection. The utility model provides a four -way multiplexing incoherent holographic device of double beam splitter annular detection, include: four groups of incident module, two optical branch and a main light path, optical branch and incident module one pair of two settings, and incident module includes plano -convex lens and half -wave plate, and half -wave plate rotatablely set up on the light path around the central optical axis, optical branch includes beam combiner and reflector, and object wave light converges to half -wave plate through plano -convex lens, and then delivers to the beam combiner of corresponding optical branch. In the utility model, the light path structure is simplified through the light path convergence section, and the cost is reduced, and through the rotatable setting of half -wave plate, the four -way multiplexing hologram acquisition under different scenes is laid the foundation, and four -way multiplexing hologram acquisition cost and operation difficulty under different phases are greatly reduced.
